S/S Header Stud Kit - 3/8in x 1.670in OAL (12)

The ARP S/S Header Stud Kit – 3/8in x 1.670in OAL (12) is a premium-grade fastener set designed for small block Chevy engine builders and performance enthusiasts who require reliability under extreme cylinder head clamping loads. This 12-piece stainless steel header stud kit provides the necessary strength and corrosion resistance for both naturally aspirated and forced-induction engine applications.

Each header stud measures 3/8 inch in diameter with a 1.670-inch overall length, optimized for small block Chevy intake and exhaust manifold mounting. The polished stainless steel construction resists corrosion and thermal oxidation while maintaining tensile strength across wide temperature ranges. The 12-point nut design ensures consistent clamping force and minimizes the risk of rounding or stripping during installation and removal cycles.

Engine builders, restoration specialists, and performance tuners working on small block Chevy platforms will find this kit essential, as header fastener failure can lead to combustion sealing issues, exhaust leaks, and power loss. Whether assembling a street engine, race platform, or long-term restoration project, this stainless steel header stud set simplifies the process of sourcing individual fasteners and ensures consistency.
